Sprint 172 Plan: C++ Diagnostic Auto-Fix for Missing Standard Includes

Context

Path B failures are currently dominated by deterministic compile errors like missing <vector> include despite emitted std::vector usage.

Goals

1. Auto-repair common missing STL includes from compile diagnostics
2. Integrate repair into strict production loop before declaring blocked
3. Keep repair deterministic and fully traceable

Steps

Step 1904: C++ include fixer from gate diagnostics (10 tests)

Implement diagnostic-driven include insertion tool:

• parse missing-header hints from compiler stderr
• add needed headers (vector, map, set, optional, tuple, memory)
• preserve include ordering and idempotency

Step 1905: Loop integration for auto-fix attempt (8 tests)

Wire include fixer into production loop:

• run fix attempt after compile/test fail
• re-run gates after fix
• trace both pre/post fix gate states

Step 1906: Sprint 172 Integration Summary (8 tests)

Add editor/src/Sprint172IntegrationSummary.h with:

• steps_completed=3
• cpp_include_autofix_active=true
• loop_autofix_attempted=true
• success=true

Architecture Gate

• Missing STL include should not require manual prompt rewrite
• Auto-fix must be auditable and idempotent
